COMBUSTIB'LE VAPORIZING CASE,

SPECIFICATION forming part of Letters Patent No. 399,230, dated March 5, 1889. Application filed June 20, 1888. ieriel No, 277,649. (No model.) Patented in England March 3, 1885, No. 2,786

To (6. 1mm it may concern:

Be it known that 1, JOHN Mounts, chemist a subject of the Queen of Great Britain, and residing at Shirley Cottage, South View, Basing'stoke, England, have invented certain lllllll'OVClllGllhS in carbon cones and cases for distributingmedicinal matters, disinfectants, fumigants, perfumes, and the like, (for which I have obtained a patent in Great Britain, No. 2,786, dated the 3d day of March, 1885,) of which the following is a specification.

Yery-finely-powdercd carbon is intimately mixed with levigated fused nitrate of potash in varying proportions with or without the addition of gum. These ingredients are then wetted and subjected to a further incorporation in a rolling and kneading mill of such power as will permit of a heavy pressure being imposed upon the mixed materials, such as will render the resultant mass homogeneous and dense in character. The proportions of the fused nitrate ot potash vary from the maximum of: twenty-five per eentunl of the quantities of the carbon used downward to five per ccntum, or less, accordingto the rate of combustion required. T he carbon may be first treated with acids or the like for the removal of certain mineral constituents and the destruction of certain impurities. At option I employ definite proportions of silicates or finely-divided glass for tempering the mixed mass of carbon and nitrate of potash with (or without) gum.

The tempering materials are used in varying proportions, usually being five per centum of the whole weight of the materials operated and cases I am able to develop and command upon. After a thoroughincorporation in the rolling and kneading mill the mass is at once worked up into cones or cases. These cones or cases are made in the desired forms, which maybe effected by means of polished gunmetal molds of the following description:

A central solid core of metal is n'ovided,v

with a highly-polished surface, either concshaped or of such other shape as will form the interior space of the desired cone or case, and a corrcspmiding hollow mold of the same metal equally polished on its in ternal surface,

the diameter of the interior solid cone or otherwise-shaped core, part for part. A portion of the mixed carbonaceous mass is then placed within the hollow mold, and is by any suitable mechanical arrangement subjected to heavy n'essnreovcr the solid internal core of metal, ahoiiow connoicasebcingthus produced whose walls are equal. These cones and cases are then. removed from the molds and are at once subjected to a dry heat of not less than 220 Fahrenheit for a space of from tive to fifteen minutes, havingregard to their varying sizes and quantities of material. The temperature then lowered to from 160' to 180 Fahrenheit, at which they are dried off. They are afterward plOYldGtl with bases made of line clay, aluminous, or any other material of such nature, such as proves incoinbustihle up to and inclusive of a temperature equaling 500 Fahrenheit, for the purpose of mitigating the effects ot-thc heat given off in the act of combustion. The apexes or tops of these cones or cases may be tipped with any quicklylighting' material to accelerate their combustion.

The imitcrials which these cones and cases are to convert into vapor are placed within the cones and cases.

In the accompanyin drawiu which forms part of this specification, A represents the carbon cone, B a glass receptacle inside the carbon cone and containing the material to be vaporized, and 0 represents the ineombustible support for the carbon cone.

It is important to notice that by increasing or decreasing the wall thicknesses of the cones a range of heat more quickly and effectually for the ends in view than by any other method, the portability of the means for so doing bein may regarded.

iy providin a case which is incomlnistible at a compaiativcly high ranp'eof temperature I obviate to a great extent injuries that may be caused by the combusi ion of carbonacemis matters for the above purposes.

I claiin- 1. The within-described cone or case for diswhose inside diameter exceeds in any part i sipating' active materials in a state of vapor,

said cone or case being composed, essentially, of carbon combined or mixed with nitrate of potash, substantially as set forth.

2. A combustible cone or case for the purpose specified, composed of carbon and levigated fused nitrate of potash, and provided with an incombustible support or base, substantially as described.

In testimony whereof I have signed my-nanie to this specification in the presenceof two subscribing witnesses.
